Internet protocol version 4-to-version 6 redirect for application function-specific user endpoint identifiers

A non-transitory computer-readable medium storing instructions which, when executed by a stack redirect function of a communications network, the stack redirect function including at least one processor, cause the stack redirect function to perform operations, the operations comprising:

• receiving, from an application function of the communications network, a redirected request for an application function-specific user endpoint identifier that is unique to a combination of a user endpoint device and the application function, where the redirected request includes an identifier of the application function and an internet protocol version address associated with the user endpoint device;
• querying a binding support function of the communications network for a subscription permanent identifier associated with the internet protocol version address associated with the user endpoint device;
• querying an application function-specific management function for an application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function;
• and
• forwarding the application function-specific user endpoint identifier associated with the subscription permanent identifier and the identifier of the application function to the application function.
